Exercise 1 Connecting to the eNodeB (RBS) at site

OBJECTIVE:

The objectives of this exercise are to: • prepare the laptop for connectivity to the eNodeB

• install the Element Manager in the site laptop

• connect to the eNodeB with the Element Manager

These objectives should be achieved by following the procedures and descriptions given in the Customer Product Information (CPI).

REFERENCE DOCUMENT:

• Customer Product Information (CPI) for L15 RBS

o User Guide: “Installing an Element Manager Application”

Follow the operational instruction to prepare your laptop for connectivity to the eNodeB.

After the task is completed, answer the following questions:

1. What is the local IP address and subnet-mask of the eNodeB?

2. What should be the default gateway configured on your laptop/PC which will connect directly to the eNodeB?



3. To which port in the DU would you connect to have a serial connection?

4. To which port in the DU would you connect to have a “fast ethernet” connection?

CONNECTING THE CABLES

After the task is completed, answer the following questions:

1. Did you have to turn off the firewall in your laptop/PC? How did you do it?

2. Which application in the laptop/PC did you use to verify that the serial connection was ok?

3. Which application in the laptop did you use to verify that the “fast ethernet” connection was fine?

CONFIGURING THE ELEMENT MANAGER

Follow the User Guide to install the eNodeB’s Element Manager application in the laptop/PC.

Exercise 3 RBS Commissioning Procedure

OBJECTIVE:

The objective of the exercise is to go through the complete procedure of commissioning an eNodeB from the site.

Depending on the preparation in the network, the requirement to upgrade, install license, the procedure might be different in a real situation. However, the questions asked here would explain how the procedure would be for different conditions.

REFERENCE DOCUMENT:

• Customer Product Information (CPI) for L14 RBS (EN/LZN 7840900)

o Description: “Add RBS”

o Operational Instruction: Integrating RBSs On-Site”

o User Description: “RBS Auto-Integration”

INSTRUCTIONS:

By either following the instructions in the reference documents or by following the instructions below, configure/integrate the eNodeB with the resources provided.

Files provided:

• Site Installation Configuration

• Site Basic Configuration

• Site External Configuration

RBS COMMISSIONING

Before starting the commissioning procedure, answer the following questions by inspecting the files provided:

1. What types of information are present in the Site Installation file provided?



2. In which of the scripts is the Network Synchronization reference solution for the eNodeB specified?

3. Which file would tell you how the CPRI connection between the Digital Unit (DU) and the (Remote) Radio Unit (R/RU) is realized? Does it match the actual hardware?

4. If license should be installed as a part of the commissioning procedure, which file would specify this requirement?

5. What will be the IP address for O&M after these scripts are loaded? Is there a VLAN used for O&M?

6. How many sectors would be defined if you ran these scripts?

7. How many cells will be defined when the integration is finished with these files?

8. Power on the eNodeB. What are the LEDs status in the DU and the R/RU?

9. Make sure that your laptop/PC is configured for connecting to the eNodeB. What is the configuration version that the RBS is executing now?

10. Start the RBS Integration tool.Fill in the details in the GUI as is applicable for the manual integration. Press “Start Integration” to start the integration procedure. Do you lose connection to the eNodeB? Why?



11. Follow the integration progress. When would “VLAN scanning” part of the progress view show some information? (Note that this is only available in L14B nodes.)

12. Assuming that the network (= OSS-RC, DNS) also sent the rest of the configuration down to the eNodeB, and the cell was unlocked, perform a data session. Verify that the Mul interface is up by pinging the OSS-RC. How did you do it?

13. Verify that the LEDs are ok, alarms are as expected. Fill in the integration report and send it up to the FTP server. Disconnect your laptop/PC and tidy up the site before leaving.

Some follow-up questions:

1. Was the procedure explained here a procedure for “manual integration” or for “auto-integration”?

2. What would have been the main difference if the “other” type of integration was required?

3. If there were other systems (WCDMA or GSM) in a RBS 6000 cabinet, then the terms Multi Standard Single Mode (MSSM) or Multi Standard Mixed Mode (MSMM) would have been used to describe the setup. Which of the following units could be shared in MSSM and/or MSMM configuration?

a) Digital Unit: _____________

b) Radio Unit: _____________

c) Fans : __________________

d) PDU (if present) : ___________________

e) TCU (if present) : ____________________



Exercise 4 Adding a new sector (Optional)

OBJECTIVE

The objective of the exercise is to understand how a new sector might be added to an existing configuration in the LTE RBS.

REFERENCE DOCUMENT

• RBS CPI

• Instructor

BACKGROUND

Sectors are added when the RBS is commissioned, and the file “SiteEquipment” (also called RbsEquipment) is used to create the confirmation of the (remote) radio unit, the sector and the antenna system. However, how should a new sector be added?

To understand how the sector is added, one must first understand which Managed Objects that must be created.

The following managed objects are relevant in the process of creating a new sector, assuming a Radio Unit is used. The remote radio unit related MOs are slightly different:

• AuxillaryPlugInUnit

• AntennaUnitGroup

• AntennaSubUnit

• AuPort

• RfBranch

• SectorEquipmentFunction

• SectorCarrier

• EUtranCellFdd

It is possible to use any tool of choice to create the MOs.



INSTRUCTIONS

Use the Element Manager (or AMOS) to create the new sector.

1. Find out the plug in unit type (MO “piuType”) for the new RU to be added. Define the new Radio Unit as a new “auxillaryPlugInUnit” under a RbsSlot.

2. Assign the proper SwAllocation to the new board that has been added.

3. Unlock the new board. Make sure that the board is operational.

4. Now, define a new “AntennaUnitGroup” and the related MOs underneath it. Examples include:

• AntennaSubUnit

• AuPort

• RfBranch

5. Create a new “SectorEquipmentFunction” and link the RfBranch(es) to the sector. Make sure that all the new sector is ‘enbaled’. Now the configuration is at the same level as the RbsEquipment is completed.

6. Define a new SectorCarrier.

7. Define a new cell (EUtranCellFdd) and unlock it.
